Question

A rectangular box has a width of x meters, length of x + 3 meters, and

a height of x 2 meters. Write an expression for its volume.

Answer 1

x*(x+3)*(x^2)

Explanation:

Width: x meters, length: x + 3 meters, height x^2 meters

It's an expression, so there's no simplifying needed.

x(x+3)(x^2)

But if I'm wrong and it's supposed to be simplified, Read the rest.

First, multiply x by x + 3

x(x + 3)

x^2 + 3x

Now, multiply x^2 + 3x by x^2

(x^2)(x^2 + 3x)

x^4 + 3x^3
